Application filed July 9, 1914. Serial No. 850,082.

To all whom it may concern:

Be it known that I, JOSEPH ZAGORA, a citi-. zen of the United States, residing at Racine, in the county of Racine and State of VVisconsin, have invented certain new and useful Improvements in Fluid Circulation Indicators and Distributers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in fluid distributers and indicators and has for its objects to provide a device of this character so constructed as to allow a number of bearings to be lubricated byfurnishing proper amounts of lubricating fluid to all of said bearings, to provide a spring pressed plunger to control an excessive pressure outlot, and to operate an indicator, to provide an overflow passage whereby leaking is prevented, to provide an air pocket in the active end of the plunger and to so form said plunger as to allow fluid trapped in advance thereof to flow around the same and to es ca ie when the supply of fluid is checked.

ith these and minor objects in view, the invention resides in certain novel features of construction and combination herein described and claimed and shown in the drawings wherein:

Figure 1 is aside view of a fluid distributer and indicator constructed in accordance with my invention;

Fig. 2 is aplan view of Fig. 1 with part of the indicatin mechanism removed and' With the indicating finger in section;

Figs. 3, 4 and 5 are vertical sections taken ondthe lines 33, 4-4 and 55 of Fig. 2; an

Fig. 6 is a horizontal section,on the line 6-6 of Fig. 1.

In the accompanying drawings I have shown my invention as including a substantially cylindrical casing 1 which is provided with an upright bore 2 whose lower end is internally threaded at 3 to receive a coupling 4- by means of which a fluid conducting pipe 5 is connected thereto, the upper end of the bore 2 being slightly contracted as indicated at 6 and being closed by an upp r end 7 of the casing, said end 7 having a central openmgES des gned for a purpose to appear.

xtending in numerous directions from the bore 2 and spaced upwardly from the coupling 4, are a number of discharge openings 9 which are formed through a flange l0 formed'on the casing 1, the outer ends of said openings 9 being threaded to receive discharge tubes 11 which may lead to the bearings to be lubricated and which may be of any desired sizes.

Located a suitable distance above the openings 9, is an excessive pressure outlet or exhaust 12, the latter projecting outwardly from the bore 2 as indicated at 13 and then passing downwardly as at 14 and receiving a fluid conducting tube 15 in its lower end.

Disposed a considerable distance above the excessive pressure exhaust 12, is an overflow or drain assage 16 which extends laterally a suitable distance and then downwardly as at 17 and receives a fluid conduct ing pipe 18 in its lower end. By reference to the drawings, it will be seen that the passages 12 and 16 are formed in upright projections 12' and 16' formed on the casing 1 and that these passages discharge through the lower ends of said extensions at which points the tubes 15 and 18 are attached.

Slidable within the portion 2 is a plunger 19 which is provided with a bore 20 on its lower side, said bore constituting an air pocket, said plunger having the diameter of its lower end reduced as at 21, these provi sions being made for a purpose to be hereinafter explained. The plunger 19 is provided with an upright operating stem 22 which rises through the reduced portion of the bore and projects through the opening 8, the upper end of said stem being loosely connected to an indicating finger 23 by means of a suitable coupling 24, said finger projecting through an opening 25 in a plate 26 and coacting with suitable indicating characters carried by a second plate 27 adjacent the plate 26 and supported in any suitable manner by the casing 1 or at any desired point where the same may be easily viewed. By reference to the vertical sections, it will be seen that a coil spring 28 is located within the bore of the casing, said spring contacting at its lower end with the plunger 19 while its upper end normally forces a. packing ring 29 snugly around the stem 22 and into contact with the closed end 7 of the casing 1. By the provision of this spring, the packing ring is retained under proper compression at all times to prevent the entrance of dust and the escape of fluid and the plunger 19 is forced downwardly ,into contact with the coupling 4 when fluid is no longer forced into the casing. When in this lowered. position, the space between the reduced lower end of the plunger and descend to an extent great enough to allowthe ports 9 to be closed, on account of the fact that fluid would be trapped between the plunger and the coupling 4.

With the' parts as above described, the operation of the device is as follows Fluid, under pressure, is admitted through the pipe 5 into the bore of the casing 1, said fluid now trapping air within the bore20 of plunger 19, and through the instrumentality of this body of air, raising the plunger to uncover the outlet openings 9 thus allowing the fluid (a lubricant in the present case) to be discharged to the various bearings of the machine to be oiled. By reference to the drawings, it will be seen that the space between the reduced end of the plunger and the wall of the bore 2 acts as a passageway from the lower end of said bore to the excessive pressure exhaust 12. Under ordinary circumstances, the openings 9 being of greater size than the passageway above mentioned, the fluid will be discharged through said openings 9, but, under excessive pressure, a considerable amount of the fiuid will pass upwardly in the above'mentioned space and will be discharged through the exhaust 12 and tube 15 into the reservoir (not shown), from which the fluid was originally forced. Still greater pressure will raise the plunger 19 to a greater extent thus allowing the fluid to more readily escape.

It has been found that considerable fluid will leak upwardly around the plunger 19 into the upper end of the'casing, this fluid being now discharged through the overflow passage 16 and the pipe 18 into the above mentioned reservoir.

It may here be explained, that due to the mounting .of the indicating finger 25, the same will be caused to swing as the plunger moves vertically, thus indicating the manner in which the lubricating system is workm lhe lubricating fluid, entering through the pipe 5, is usually forced by a pump, the latter causing the body of oil to violently 'pulsate, especially if the pump be of the reciprocating type. It is to prevent these pulsations from being transmitted directly to the indicator that I have provided the bore 20 in the plunger 19, said bore, as above stated, acting as an air pocket which air acts as an efficient cushioning means for preventing the above mentioned'objectionable feature.

As clearly seen in the drawings, the cas- 'ing 1 is provided with a horizontal attaching foot or plate30 through which bolts or screws may be passed for the purpose of rigidly supporting the device in proper position upon a suitable support.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that I have produced an extremely simple fluid distributer which will e'fi'ectually perform the functions for which it is designed and which may be inexpensively manufactured. It will also be noted that the stroke of the plunger is rather long thus imparting an appreciable amount of movement to the indicator.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the clainied invention, and it may well be employed on internal combustion engines such as those used on automobiles, in which engines, the oil feed fluctuates constantly on account of the necessity of varying the speed of the engine and consequently that of the pump driven thereby.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. An oil distributer comprising a hollow body having respectively near its two ends a plurality ofoil distributing openings of predetermined size and a vent, an inlet into the end of the body adjacent the distributing openings, a piston slidable in the body between the inlet and the vent, and means for preventing movement of said piston beyond the vent.

2. An oil distributer comprising a hollow body having respectively near its two ends a plurality of oil distributing openings of predetermined size and a vent, and having between the vent and the openings an ex cessive pressure outlet, an inlet into the end of the body adjacent the distributing openings, a. piston slidable in said body between the inlet and the vent, and means for preveniting movement of said piston beyond the ven 3. In combination, a hollow body having near one end a pressure outlet, an inlet into such end of the body, and a piston in said body for controlling the outlet, said piston bearing normally on said end of the body and being reduced in diameter from such end to an intermediate point spaced from the latter a distance approximately equal to the distance between the same and the oil distributing openings. the piston being adapted to actuate an indicator.

4. In combination, a hollow body having in its wall at a point spaced from one end,

, in its lower end apressure inlet and having a fluid outlet, an automatically cont-rolled in its wall a pressure outlet, and a vertically disposed automatically controlled tubular piston in the body and contacting therewith, said piston having its lower end open and having its upper end tightly closed, whereby a body of air may be trapped in said piston to serve as a cushion, thereby compensating for a fluctuating pressure without continually jarring the piston, the latter being therefore well adapted for operating an indicator.

6. In combination, a hollow body, an automatically controlled piston therein in substantially fluid tight contact with the wall thereof, a fluid pressure inlet into' the body adjacent one end of the piston, and a. assage from said body near the other end of said piston, for draining from the body any fluid which may leak past the piston, the

last named end of the piston having an extension protruding through the adjacent end of the body.

7. In combination, a hollow body having at one end a pressure inlet and inits wall piston inthe body in contact therewith and sliding over said outlet to control the same, said piston having one end hollowed out whereby a body of air may be trapped therein to serve as a cushion to avoidrapid pulsation with a fluctuating fluid supply.

8. In combination, a hollow body having at one end a fluid inlet and adjacent said inlet a fluid outlet, a piston free from ports and normally resting at one end on the inlet end of the body and reduced in diameter from said end to a point near the outlet, whereby the space between the reduced end of the piston and the body thereof may serve as a by-pass for fluid when the regular flow is interrupted, thus allowing the piston to overlap the outlet to obtain a long piston travel.

9. In combination, a hollow body having near one end a pressure outlet, an inlet into such end of the body, a piston in and contacting with said body, one end of said piston resting normally at the aforesaid end of said body, a small peripheral space or clearance being provided between the body and said end of the piston, this space being of a length approximately equal to the distance between theinlet and outletto permit a a slow escape of trapped liquid.

l 1.0. In combination, a hollow body having a fluid inlet in one end and an outlet in its wall, a spring resisted piston in said body free from ports and normally resting at one end on said end of the body, said end of the piston being reduced slightly in diameter to permit the escape of trapped liquid through said outlet, the other end of said piston having a stem extended through the end of: the body remote from that having the inlet.

11. The combination of a cylinder having a fluid inlet at one end and an outlet in its wall, a piston in said cylinder hollowed out to form an air compression chamber open at the end adjacent said inlet and closed at its other end, said piston sliding over and closing said outlet when the supply of fluid is stopped and opening said outlet when shifted by continued flow of the fluid, the closed end of said piston having an extension movable bodily therewith and projecting through the cylinder.

12. In combination, a hollow body having a. fluid inlet at one end and an outlet in its wall, a spring resisted piston in said body free .from ports and normally resting at one end on said end of the body,the other end of said piston having a stem extended through the end of the body remote from that having said inlet.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
